Hana to hebi (1974)

Hana’s the main woman here — early 20s, petite Asian frame, long black hair, slim build. She starts off alone on a bed in a dark bedroom, touching herself, spreading her legs, close-up shots of her fingers working her pussy. Then the guy shows up — 30s, short black hair, muscular Asian build, not overly bulky but looks strong. They go from there to skin-on-skin contact, him going down on her with his face buried in her crotch for extended oral. She returns the favor with a slow, deep blowjob, head bobbing, guy groaning. Camera stays tight during the sex, dim lighting, red tones giving it a moody, intimate vibe. Most of the action happens in bed, missionary position, some side shots showing thrusting and her reactions. No wild acrobatics, just steady, up-close fucking and oral with a focus on sensation.
